Dispersant compositions containing a diisobutyl ester of a dicarboxylic acid and a polyurethane-based dispersant

摘要

Dispersant compositions are described which contain: (a) a carrier medium comprising a ternary mixture of diisobutyl esters of succinic acid, glutaric acid and adipic acid, the carrier medium present in an amount of from 10 to 80% by weight based on the composition; and (b) one or more polyurethane dispersants present in an amount of from 20 to 90% by weight based on the composition.
